[0035] To facilitate understanding of the EMU control circuit for a prefabricated energy storage module in a photovoltaic-storage-diesel microgrid provided in this application embodiment, its application scenario is first explained. The EMU control circuit for a prefabricated energy storage module in a photovoltaic-storage-diesel microgrid provided in this application embodiment is used to improve the reliability and safety of EMU control circuits. Existing EMU (Energy Management Unit) control circuits for prefabricated energy storage modules in microgrids are generally integrated with the energy storage unit. While this integration improves the system's compactness and efficiency, it also has some drawbacks: Cost and maintenance complexity: Due to the integration of the EMU control circuit with the energy storage unit, this highly integrated system often means higher R&D and production costs. This is mainly because integrated systems require more refined design and manufacturing processes, as well as higher quality materials and components. Maintenance of integrated systems also becomes more complex.

Limited system flexibility and scalability: The integrated EMU control circuit and energy storage unit may limit system flexibility. As microgrid scales up or energy storage demands increase, more energy storage units and more complex control circuits may be required, but integrated systems may struggle to adapt to these changes. Fault detection and diagnosis become more difficult: In integrated systems, the interaction between the EMU control circuit and the energy storage units can make fault detection more challenging. Due to the high degree of system integration, a single fault may involve multiple components or subsystems, increasing the difficulty of diagnosis and repair.

[0038] The EMU controller includes a diesel generator control unit and a power conversion control unit, wherein...

[0039] The diesel generator control unit is electrically connected to the third relay KA3;

[0040] The power conversion control unit is used to control the emergency shutdown of the power converter.

[0041] In the above technical solution, an enclosure is installed, housing an EMU controller. The EMU controller includes a diesel generator control unit and a power conversion control unit, the latter being electrically connected to a third relay KA3.

[0042] Specifically, by setting up an enclosure and installing an EMU (Energy Management Unit) controller containing a diesel generator control unit and a power conversion control unit inside the enclosure, the beneficial effects include:

[0043] I. The beneficial effects of electrically connecting the diesel generator control unit with the third relay KA3

[0044] Enhance control flexibility:

[0045] The diesel generator control unit is connected to the power system or other control equipment via the third relay KA3, enabling flexible remote or local control. This design allows operators to adjust the diesel generator's operating status, such as starting, stopping, and speed adjustment, as needed.

[0046] Improve system security:

[0047] Electrical isolation via relays effectively prevents system short circuits or damage caused by electrical faults. Simultaneously, the diesel generator control unit can monitor the diesel generator's operating status in real time; upon detecting any abnormality, it immediately cuts off the power supply via relays to protect system safety.

[0048] Facilitates maintenance and troubleshooting:

[0049] Relays are common electrical components, and their troubleshooting and maintenance are relatively simple. When a fault occurs in the diesel generator control unit or related circuits, operators can quickly locate the problem and perform appropriate repairs or replacements by checking the status of the relays.

[0050] II. Beneficial Effects of the Power Conversion Control Unit

[0051] Implement emergency stop function:

[0052] The power conversion control unit monitors the operating status of the power converter. Upon detecting an anomaly or receiving an emergency stop command, it immediately cuts off the power to the power converter to prevent the fault from escalating or causing more serious consequences. This design is crucial for ensuring the stable operation of the system and the safety of personnel.

[0053] Optimize energy management:

[0054] The power conversion control unit can also intelligently adjust the output power and conversion efficiency of the power converter according to the actual needs of the system. This intelligent energy management function helps to optimize energy allocation and save energy, thereby improving the energy efficiency of the entire system.

[0055] Enhance system compatibility:

[0056] The EMU controller integrates standard acquisition protocols and interfaces compatible with major equipment manufacturers, enabling the power conversion control unit to easily connect to various types of power converters and energy management systems. This design enhances system compatibility and scalability, facilitating future upgrades and expansions.

[0057] III. Overall Beneficial Effects

[0058] Improving overall system performance: By integrating the diesel generator control unit and the power conversion control unit, the EMU controller enables comprehensive monitoring and management of the diesel generator and power converter. This integrated design helps improve the overall system performance and stability, reducing failure rates and maintenance costs.

[0059] Facilitates centralized monitoring and management: The EMU controller can be easily connected to a remote monitoring system via its built-in communication interface. This allows operators to monitor the system's operating status in real time from a remote location, adjust control strategies, and troubleshoot faults. This centralized monitoring and management approach improves the system's operability and maintainability.

[0060] In summary, by setting up a cabinet and installing an EMU controller containing a diesel generator control unit and a power conversion control unit inside the cabinet, beneficial effects such as enhanced control flexibility, improved system safety, easier maintenance and troubleshooting, emergency shutdown function, optimized energy management, enhanced system compatibility, and improved overall system performance can be achieved. Together, these improvements enhance the reliability and energy efficiency of applications such as photovoltaic-storage-diesel microgrid energy storage prefabricated cabins.
